PAM8606
6W Stereo Class-D Audio Power Amplifier with DC Volume Control
Key Features
General Description
The PAM8606 is 6W (per channel), stereo class-
D audio amplifier with DC Volume Control which
offers low THD+N (0.1%), low EMI, and good
PSRR, allowing it to produce high-quality sound
reproduction. The 32 steps DC volume control
has a +32dB to -75dB range.
